OSRS Help with Poesy700's cache tool

I'm trying to load a 166 cache into Poesy700's cache tool but for some reason the cache isn't loading up. I'm looking to dump all the item, npc, sequence files into a .txt (not .dat) to be added to a 317 (similar to all the cache dumps released by Ian). Hopefully this is that right tool for that. Need for Vorkath and Galvek's animation definitions.
